property 'storageAccountIdentity' doesn't exist for lines 98 and 99

### Repro steps (*if necessary, delete otherwise*)
1. Copied code from template into my repo
2. Ran code via CICD pipelines
3.Got the following error:

InvalidTemplate: Unable to process template language expressions for resource '/subscriptions/123/resourceGroups/my-rg/providers/Microsoft.Resources/deployments/addAccessPolicy' at line '1' and column '3725'. 'The language expression property 'storageAccountIdentity' doesn't exist, available properties are 'apiVersion, location, sku, tags, properties, condition, deploymentResourceLineInfo, existing, isConditionTrue, subscriptionId, resourceGroupName, scope, resourceId, referenceApiVersion, isTemplateResource, isAction, provisioningOperation'.'

Start with quickstarts/microsoft.databricks/databricks-workspace-with-customer-managed-keys/azuredeploy.json, especially lines 98 and 99, and inspect the resource reference used by the addAccessPolicy deployment. Reproduce the deployment error through the reported CI/CD path; done means the template deploys without the missing storageAccountIdentity property error.
